Classification Code

Classification codes are the foundation of insurance pricing. Every type of business is assigned a code based on its operations, and each code carries a base rate per unit of exposure (typically per $100 of payroll for workers' comp, or per $1,000 of revenue for GL). Tree service companies are usually assigned specific codes that reflect the high-hazard nature of the work — for example, NCCI class code 0106 for tree pruning or surgery operations in workers' compensation.

Getting the right classification code matters enormously. If your company is misclassified into a lower-risk category, you may enjoy lower premiums initially, but a premium audit will catch the error and result in a large retroactive charge. Conversely, if you are classified too aggressively — for example, lumped into a general "logging" code when you only do residential tree care — you may be overpaying. Your agent should verify that your classification accurately reflects your actual operations.

Many tree service companies perform multiple types of work, each with its own classification. You might have one code for tree trimming and removal, another for stump grinding, and a third for lawn maintenance or landscaping services if you offer those. Properly splitting your payroll or revenue across the correct codes ensures accurate pricing and prevents audit surprises.

Classification codes also affect your ability to get coverage in the first place. Some carriers will not write certain high-hazard codes, while others specialize in them. When your agent markets your account, the classification code is one of the first things an underwriter sees. A code associated with tree trimming near power lines, for instance, immediately signals a high-risk account that many admitted carriers will decline.
